Correction, 7 September 2026: This announcement has been updated to explain what Country Block does and the limits of IP-based filtering. Earlier promises of perfect accuracy, zero overhead, and impenetrable protection were not substantiated.
Country Block is a WordPress plugin for country-based access rules. It uses a local MaxMind GeoLite2 database to associate a visitor’s IP address with an estimated country, then applies the rules you configure.
What you can configure
You can select countries to allow or block, add exceptions, and choose a block message or redirect. Optional logs help investigate blocked requests. Read the plugin listing for the current requirements and settings.
What country blocking cannot prove
An IP-country result is not proof of a person’s physical location, identity, nationality, or intent. Shared connections, mobile networks, and VPNs can change the country associated with a request. A country rule can block a legitimate customer and still allow an attacker using a different network.
Geo-blocking is one access control. It does not replace strong authentication, updates, backups, or a complete assessment of legal obligations.
Check your cache before relying on a rule
A CDN or server cache can serve a page before WordPress runs. Test while logged out from an allowed and a blocked location, and review protected URLs with your host. Configure cache bypasses or suitable rules at the CDN where needed. Check forms, login, checkout, and search-crawler access.
Local lookup and data handling
Country lookups use the local database rather than sending every visitor IP to MaxMind. Database downloads contact MaxMind using your license key. Optional logs still contain visitor data, so review the logging, anonymisation, and retention settings.
Country Block or VPN Guard?
VPN Guard checks VPN, proxy, Tor, and relay classifications through vpnapi.io. Country Block focuses on estimated country. If you use both, test their combined rules and exceptions; neither provides perfect detection.
